Due to the capital investment cost, procurement and construction schedule, as well as permissions and environmental restrictions, oil and LNG terminals tend to move more offshore nowadays. Survivability of the facility and operational downtime becomes an issue because of the considerably more challenging metocean conditions. A precise wave forecast at the terminal site becomes more critical than ever for terminal planning and operation.
This paper describes a wave forecast method to estimate site specific conditions. Qualitative evaluations on the effects and confidence provided to the terminal operation will be presented in case studies.
